In mid-June, when the villagers of Huaqiao Village were busy harvesting rice, Hua Qingcheng also drove a rice harvester and harvested the first batch of mature rice in her space.

The growth cycle of crops in the space is much shorter than that in the outside world. This time when Hua Qingcheng returned to the space, she found that there was a large row of warehouses outside the villa.

After harvesting the mature rice, Hua Qingcheng first threshes the rice with a thresher, and then uses a rice dryer to dry the rice until the moisture content of the rice is reduced to a safe storage moisture content of 12% before storing it in a warehouse.

Not only grain, Hua Qingcheng also dried the straw left after harvesting the rice, and then piled them all neatly aside to be used as fertilizer for the Hua family farmland outside the space in the future.

After a rough calculation, Hua Qingcheng found that the yield of rice planted in the space reached 3,000 jin per mu, which means that she harvested almost jin of rice from the first batch of rice she planted.

Seeing the good results, Hua Qingcheng not only leveled the original 10 mu of rice field with a rotary tiller, but also reclaimed an additional 20 mu of rice field. She then took some rice grains for seeds and used them to grow rice seedlings.

A month had passed since Hua Qingcheng arrived in Laifeng Country, and she'd discovered there were no sweet potatoes. Remembering the sweet potatoes and potatoes piled in a corner of her villa's kitchen, Hua Qingcheng took them out and planted them on the land in her space. These were high-yield crops, life-saving in a critical moment. In this alien world, there was no telling which would come first, an accident or tomorrow, so Hua Qingcheng figured it was a good idea to stockpile extra supplies.

Seeing the villagers still threshing rice with the extremely outdated threshing method of beating, Hua Qingcheng felt exhausted. Thinking that the Hua family's land would soon be ready for late rice cultivation, Hua Qingcheng searched for information on threshing machines on her computer. Based on the local productivity level, she used charcoal pencil to draw a design for a foot-operated threshing machine.

After finishing the design drawings of the thresher, Hua Qingcheng also searched for the production method of the wind cabinet and drew the detailed drawings with charcoal pencil.

"Wife, it's time for lunch!"

At noon, there was a knock on the door from Mu Lige. Seeing that Hua Qingcheng had stayed in the room all morning and did not come out, Mu Lige came to knock on the door worriedly.

“Here I come!”

After Hua Qingcheng pressed the blueprint onto the table with a small stone, she followed Mu Lige to the main hall in the front yard for lunch. Mu Lige had prepared three dishes and a soup for lunch, and everyone was full of praise.

"Li Ge, come with me to Aunt Qian Yi's house later."

"Okay, is there anything I can do?"

Mu Lige was a little confused when Hua Qingcheng suddenly suggested going to Qianyi Carpenter. However, Hua Qingcheng just gave Mu Lige a sly smile and said two words: "Secret".

Soon, Mu Lige brought Hua Qingcheng to the home of Qianyi Carpenter in the village.

"Auntie, can you do this?"

In the yard, Hua Qianyi was holding the design drawings of the thresher and wind cabinet. Her hands were trembling slightly, and she didn't speak for a long time. Hua Qingcheng couldn't help but ask.

"Wonderful! Wonderful!"

Hua Qianyi looked at Hua Qingcheng with eyes that gleamed slightly. Compared to the primitive threshing method currently used by the villagers, which easily caused grains to fly all over the place, if this new thresher was manufactured, one would only need to step on the rice stalks with one foot and hold the rice ears with one hand, sweeping back and forth on the gears of the thresher, and then use the rolling gears to scrape the grains off the rice ears. This would save time and effort, and would greatly improve the efficiency of rice harvesting.

Moreover, this wind cabinet is also a good thing. Just pour the rice into the funnel on the top and gently turn the rocker with your hand to sift out the empty rice husks. It is simply an ingenious invention.

"Qingcheng! I didn't expect you to be so smart and even think of this! If you can make the gears and the connecting belt, I think it's feasible."

"Okay, I'll go to the blacksmith shop in town and ask that this afternoon."

Hua Qingcheng remained calm and collected in the face of Hua Qianyi's praise. Eager to finish the product, Hua Qingcheng and Mu Lige walked directly to the town, which took about the same amount of time as taking an oxcart, though a bit more tiring.

"How about this, can we do it?"

In Baishui Town, in Muyang's blacksmith shop, Hua Qingcheng was asking a strong man in his thirties.

Moliqi, a tall and strong man with a full beard, took a look at the drawings and was shocked. The design was indeed very ingenious and he couldn't help but stare at it for a while.

“Cough cough cough…”

Seeing that the other party was stunned, Mu Lige couldn't help but remind him.

Mo Liqi realized that he had lost his composure and looked meaningfully at Mu Lige beside Hua Qingcheng. When he saw the other party blink at him, Mo Liqi said:

"Of course, you can, but you have to pay half of the deposit first and come back in three days to pick it up."

"good!"

Seeing the other party's agreement, Hua Qingcheng readily paid 500 wen as a deposit. There was no other way. In ancient times, iron was a precious commodity and was strictly controlled by the government. Making an entire thresher would probably cost around one or two taels of silver. However, the better-off families in the village could still afford it.

After resolving the issue that had been bothering her, Hua Qingcheng was in a good mood. She took Mu Li and Liu Yuege to visit Baishui Town again.

On the morning of June 18th, Hua Qingcheng and Mu Lige took Yu Qingyou's ox cart and arrived at Mu Yang's blacksmith shop in Baishui Town as scheduled. They took away the custom-made gears and other items and brought them back to Huaqiao Village.

Seeing that Hua Qingcheng had really made those things, Hua Qianyi was very excited and quickly put the gears and other items into the finished barn cabinet. In order to experience the results, she even moved the thresher to her own rice field to try it out, and the effect was indeed very good.

"Qingcheng! If this thresher can be popularized, it will be a great achievement for us ordinary people who rely on the weather for our livelihood!"

Hua Qingcheng didn't care about this and had no intention of keeping it to herself. After all, it was not something she invented herself, so being able to help others was also a good deed.

"It's up to you, Aunt Qianyi. I don't mind this."

In just a few days, news of Hua Qingcheng's invention of a new thresher spread throughout Huaqiao Village. Since Hua Qingcheng's land wasn't currently used for rice cultivation, it was borrowed by other villagers. Every day, the thresher appeared in the rice fields of Huaqiao Village, attracting a large crowd of onlookers.

Some villagers who actually benefited from it also had a slightly improved view of Hua Qingcheng. They never expected that a second-rate person like Hua Qingcheng would one day benefit the villagers of Huaqiao Village.
